Once broken, it cannot be re-established and democrat presidents will face the same hounding every day of their lives. Quid Pro will likely step in with a pardon "for the healing of the nation" or some such.We have a long tradition of leaving a president alone once he leaves office,
We've had many long traditions go away in the last 4 years, Like the non violent transfer of power and not trying to shut down Congress while it is in joint session counting the EC votes. Another long standing tradition we've had for hundreds of years was broken after Trumpy was recorded attempting voter fraud in Georgia.
So I hope we break that one too.
